jimthompson5910 (jim_thompson5910):

which problem are you on?

OpenStudy (anonymous):

i havent started im so lost

jimthompson5910 (jim_thompson5910):

ok let's start with 1a

jimthompson5910 (jim_thompson5910):

5 - 8i is in the form a+bi, agreed? or no?

OpenStudy (anonymous):

yes

jimthompson5910 (jim_thompson5910):

what are the values of 'a' and 'b'? hint: it might help to rewrite `5-8i` as `5 + (-8)i`

OpenStudy (anonymous):

a is 5 and b is 8?

jimthompson5910 (jim_thompson5910):

a = 5 is true b = 8 is false
